The large 12-station heavy-duty turret features 5.5 kW

a large diameter Curvic coupling and heavy-duty design with unsurpassed rigidity. Turret rotation, acceleration, and deceleration are all controlled by a reliable high-torque servo
motor. Unclamp and rotation are virtually
simultaneous. Its fast index response reduces the cycle time required to machine parts.

The new rotary tool head confirms the high rigidity and accuracy by
simultaneous dual contact between the rotary tool head face and the holding insert called Preci-Flex adapter flange face as well as tool head
pocket taper and the insert taper shank,

The front door opening is detected and locked by CE certified safety
switch. All the automatic operations are only effective at the door-closed
status for operator safety. Higher performance, lower hazard. The operator’s risk is minimized
through upgraded safety produced through hazard analysis, FMEA
analysis, and human engineering design.

Widely spaced guideways and heavy-duty design of the tailstock body ensure ample rigidity. The tailstock body is positioned by a drive bar, which engages with the carriage. The drive bar movement and hydraulic body clamping are manual or programmable options.
Each axis is powered by a maintenance-free digital AC servo motor. High tailstock specification torque drive motors are connected to the ball screws without intermediate gears for quiet and responsive slide movement with virtually no backlash. The X-axis features a doubly pretensioned ball screw, supported on each end by precision class P4 angular contact thrust bearings. Both axes are driven by large diameter, high precision ball screws. Each ball screw has been carefully selected to achieve a combination of high accuracy, high rapid traverse rates, and high feed thrust. All ball screws are firmly supported at both ends.

The gantry system makes the PUMA 240 series integrated perfectly with a high-speed gantry loader. The result is a superior automated turning center, PUMA 240 series, that will increase productivity in both short and long production runs. It has a dual gripper system of 3-jaw for flange and 2-jaw for shaft to get fast workpiece exchanges and workstockers capable of large parts with 14-station.

The slant angle bed and guideways allow easy chip disposal with all types of chips, ensuring easy loading, changing, and inspection of tools. Additionally, replacing lubricants can be carried out at the front of the machine.
Perfect integration with the care environment of human and earth, reducing waste and oil contamination during the lifetime of the machine. Another suggestion to prolong the life of the coolant water and reduce grime and offensive smell inside the machine: a belt-driven type oil skimmer picks up and removes waste oil from the coolant tank, which is easily drained.

Rigorously designed, manufactured, and tested, machine covers do not permit coolant leakage in any condition. The factory always keeps our environment clean.

High compact CNC is realized through LCD display with integrated CNC, and a flash memory card interface is standard.
It provides many support functions for set-ups, such as tool measurement, workpiece measurement at the original point, and workpiece measurement inside the machine.
Uses one display screen to perform all operations, including programming, checking by animation, and real machining.

Guide for machining preparation
In preparation for machining, simple instructions on a selected screen allow measuring the setting workpiece and tool offset value for automated adjustment.
Easy operating system designed for different machines in our products. We have supplied ease of operation and high reliability with a user-friendly interface to customer production lines.

Easy operation system
Machining condition selecting function
One single screen provides handy operation guidance for programming through machine operation. Parameter setting for high speed and high precision machining instructions.
For machining centers, turning centers, and compound machines with milling, registration of parameter sets for high-speed machining and turning. Precision solid modeling provides high-speed animation, instruction of precision levels for desired machining, and selecting appropriate cutting tools.
Machine programming is easy with sophisticated parameters, automatically applied with the appropriate programming steps for turning and milling.

Measurement cycles provide automatic offset measurement of workpieces, available for machining centers and compound machines.

Note: Over tooling system is our recommendation. Depending on export conditions, the standard tooling packed with the machine may differ.
